Method for slowing down aging of copper and copper alloy ultra-fine wires

Номер: CN116024424A
Автор: CHENG TIANCI
Принадлежит:

The invention discloses a method for slowing down aging of a copper and copper alloy ultra-fine wire, aims at slowing down performance reduction of the ultra-fine wire in storage and use processes, and belongs to the technical field of copper and copper alloy ultra-fine wire processing. The method mainly aims at copper and copper alloy ultra-fine wires with the wire diameter smaller than or equal to 0.05 mm, the technical effect of relieving aging of the copper alloy ultra-fine wires is achieved under the condition that a small amount of tensile strength is lost by measuring the grain size G and the wire diameter D of the ultra-fine wires, introducing a dimensionless numerical value D/G and selecting specific low-temperature heat treatment parameters according to the D/G value; the storage and use time of the material is prolonged.
